Lecture I

It was in the middle and second half of the nineteenth century that materialism had its period of greatest development. In today's lecture we will center our interest more on the theoretical side of this materialistic evolution. A great deal of what I shall have to say about the theoretical aspect can also be said in almost the same words of the more practical aspect of materialism. For the moment, however, we will leave that aside and turn our attention more to the materialistic world conception that was prevalent in the civilized world in the middle and second half of the nineteenth century.
